An interesting series of questions from our support mailbox:
Hi Now SMS Technical Support,
Hope you are all keeping well.
Just had a question. Is there any way to define a sender ID for MMS where the leg out to the SMSC seems to have no Calling Party Address?
Define a “Default Sender Address” under the properties for the SMSC connection.

We’ve had a few inquiries related to the UCP protocol recently. UCP is a legacy application to SMS protocol that was implemented by SMSCs from a company named CMG. (Bryce posted some background info on this over 12 years ago in response to questions in our support forum at https://support.nowsms.com/discus/messages/1/8150.html)

Back in 2003, we posted an example PHP script for sending MMS via NowSMS on our discussion board at http://www.nowsms.com/discus/messages/1/1113.html.
While this script has worked well over the years, it has a serious limitation in that it does not support SSL/TLS. Version...

We have been testing NowSMS and NowSMS Lite with preview editions of Windows 10 for months.
However, today’s release version of Windows 10 presents two issues that we did not encounter with the preview releases.
For a new installation, NowSMS and NowSMS Lite 2014 and 2015 versions will both function correctly under Windows 10. There are no special considerations.

NowSMS 2-way applications are usually built on web technologies, using PHP or ASP.Net scripting. But we do get a fair number of support questions from customers who want to use VBScript.
The advantage of VBScript is that there are numerous examples available for interfacing with Microsoft Office, especially Excel, and no extra programming tools or environments are required.
As a starting point...

This post is for the information of any customers using SSL/TLS server functionality in NowSMS.
The industry has deprecated the use of SHA-1 signed server certificates, in favor of a more secure algorithm known as SHA-256. SHA is a popular hashing algorithm used by the majority of SSL certificates. As computing power has increased the feasibility of breaking the SHA-1 hash has increased. Plans...

When implementing an MMSC for a mobile operator network, one of the most confusing concepts is how user authentication is usually performed in conjunction with a WAP Gateway.
MMS uses the MM1 Protocol (OMA MMS Encapsulation) for transactions between a mobile device and the MMSC. This protocol does not define how the MMSC identifies and authenticates the subscriber when the MMS client on a mobile...

We have recently encountered 2 different scenarios where SMS and MMS messages could be sent, but not received for 2-way command processing.
A key indicator of this problem is when the “SMS Received” counter in the Android app increases, but the “SMS Received” status at the NowSMS server remains blank.
There are two types of configurations that may experience this...

We’ve posted an interim release of Now SMS/MMS with some additional features requested by customers using Android phones as modems. It should be noted that most Android modems do not support special binary SMS message types such as WAP Push. This update adds support for binary SMS message types with Android modems, but only for HTC phones, or rooted phones, as described below.
